An Examination of Driving Exposure, Habits and Harsh Braking Events in Older Drivers with Bilateral Cataract Using Naturalistic Driving Data

The aim of this study was to examine driving exposure, habits and harsh braking events in older drivers with bilateral cataract using naturalistic driving data. Ninety six older drivers aged 55+ years were assessed in the month prior to first eye cataract surgery. Data collection consisted of a researcher administered questionnaire, a cognitive test and visual measures including visual acuity, contrast sensitivity and stereopsis. Participants' driving exposure, driving habits and harsh braking events were measured using an objective in-vehicle driver monitoring device. A multiple linear regression model was undertaken to examine predictors of driving exposure in older drivers with bilateral cataract. After controlling for potential confounding factors, only binocular contrast sensitivity (p
